USE OF ADAPTORS, EXTENSIONS AND UNIVERSALS
Anytime an adaptor, extension or universal is used with a torque wrench in such a way that fastener
distance is different than torque wrench square drive distance at calibration, an adjustment to head
length is required to get a proper fastener torque reading.
When using wobble extension or a universal, do not exceed more than 15 degrees of offset from
perpendicular drive. Do not use a long extension with flex-drive at full flex.
CALIBRATION
Contact your Snap-on sales representative for calibration services or refer to ControlTech
TM
Micro
Calibration Manual.
CERTIFICATION
This torque wrench was calibrated at factory using torque measurement instruments that are
traceable to National Institute of Standards and Technology (N.I.S.T.). Torque parameters comply with
ISO 6789:2003 and ASME B107:300-2010 (B107.29). Note: no U.S. or International Standards exist for
angle wrenches. Angle calibration was performed on an angle gage with ±1 degree accuracy at each
45 degree indexing point throughout 180 degrees of rotation.
MAINTENANCE / SERVICE
Clean wrench by wiping with a damp cloth. DO NOT use solvents, thinners or carburetor cleaners. DO
NOT immerse in anything.
Service and repairs are to be done by Snap-on Service Centers only. Contact your Snap-on Tools
representative.
Ratchet head repair kits can be ordered from a Snap-on Representative.
NOTES: - If display shows persistent "TORQUE ZERO ERROR" at power on, wrench is damaged and
must be returned for repair
- If display shows “ANGLE ERROR” in angle mode, fastener rotation speed has exceeded
capacity of wrench.
- Wrench must be held still during angle zeroing. Motion is indicated by alternating dashes “-
-” on display
- Remove battery when stored for extended periods (Note: clock will revert to default
settings).
